How do I apply Crystal Plex pond algaecide?
The best way to apply liquid copper sulfate is to do a broadcast spray. Spray the algae mats with Crystal Plex in sections. You will only treat 1/3 to 1/2 of your pond at a time to prevent oxygen depletion. See labeled instructions for application amounts and click here for how tomeasure. The algae will brown up within 48 hours. Copper Sulfate is toxic to Koi, goldfish and trout.
Will Crystal Plex hurt fish or animals?
Crystal Plex liquid copper sulfate and Copper Sulfate granular is safe for livestock, recreation, potable water and not harmful to most fish when used according to label directions. Oxygen depletion is the common cause for a fish kill. There are a few exceptions, Copper sulfate is not meant for small deco ponds and is toxic to Koi, Golfish and Trout.
When do I use Crystal Plex?
Crystal Plex Algae killer, should be applied when you first notice an algae bloom. Typically algae will turn water green, have a slimy film, or thick "horse hair" like mats on the pond. Spot treat with Crystal Plex, liquid copper sulfate as needed waiting 5 to 7 days between treatments. Water tempurature must be 50 degrees or above in order to work effectively.
How often do I need to use Crystal Plex?
Crystal Plex, liquid copper sulfate algae killer, can last in water column for up to 30 days; however, solution can weaken due to rainflow, outflow and evaporation. You may need to add more if you have another algae bloom. Wait a week between applications and only treat a 1/2 or 1/3 of the pond at a time to recover oxygen levels.
How much Crystal Plex should I use?
Properly measure your pond to find the square acreage and average depth. One gallon of Crystal Plex, liquid copper sulfate solution will treat a surface acre 1 to 2 feet deep. Example: 1/2 acre pond 4 feet average depth, mix 1 gallon with 8 to 10 gallons of water. (Water is to help spread the product, not to dilute.) See labeled instructions for all application rates.
Will Crystal Plex still work if it freezes?
Yes, Crystal Plex is still effective in killing algae at the same application rate after it has been frozen. Freezing affects the residual control for Crystal Plex. Crystal Plex normally has a residual control of over a month. Frozen Crystal Plex will only have a residual effect in controlling algae for 3-5 days. When using frozen Crystal Plex be sure to shake well before diluting and spraying algae for control. I recommend using warm water to dilute the frozen Crystal Plex before spraying.

Chrystal Plex Algae Control
By Richard on 07/06/2018
I purchased this product in an attempt to deal with a major algae bloom in an approximately 1-1/2 acre pond behind my residence in southwest Florida. The product use information seemed to be directed at large scale use, perhaps spraying from a boat. Trying to determine the proper amount of concentrate to be diluted in a 2-gallon garden tank sprayer was much too difficult. Spraying near shore from shallow water using the tank sprayer was the only reasonable option. Despite trying different dilutions and different spray densities, I found no detectable change in the sprayed areas of the algae bloom. I additionally tried spraying the diluted product into the plastic tub reservoir for a decorative outdoor fountain and found no decrease in the algae.

According to the manufacturer, Crystal Plex Algae Control is not meant to be used in pools. If you were to do so, the chemical reaction between the two will cause the water in the pool to turn to an ugly red color.
